56# Read the ISO 3166 country code database in _PATH_ISO3166:
57# 	/usr/share/misc/iso3166 on FreeBSD
58# 	/usr/share/zoneinfo/iso3166.tab on Linux, Mac OS X, and Cygwin
59#
60# The format of this file on FreeBSD is:
61# 	two	three	number	name
62#
63# The format of this file on Linux, Mac OS X, and Cygwin is:
64# 	two	name
65#
66# With each of the following elements (described below) being separated by a
67# single tab character:
68#
69# 	two      ISO 3166 2-character country code
70# 	three    ISO 3166 3-character country code (if provided)
71# 	number   ISO 3166 numeric country code (if provided)
72# 	name     Human-readable country name (may contain spaces)
73#
74# Variables created by this function:
75#
76# 	COUNTRIES
77# 		A space-separated list of 2-character country codes.

79# 		The country `name' (as described above).
